For years, FPV (first-person view) drone pilots have been forced to compromise—either embrace the clarity of digital video or the speed and responsiveness of analog systems. But DJI has shattered this trade-off in 2025 with the release of the O4 Air Unit Pro.
This featherlight transmission and camera system—just 32 grams—offers a robust leap in both visual quality and flight performance, targeting both elite racers and professional aerial filmmakers.
After countless flights through urban mazes, open fields, and under harsh lighting conditions, one thing is clear: the DJI O4 Air Unit Pro isn’t just an upgrade. It’s a complete overhaul of what’s possible in FPV aerial capture. Here’s how DJI pulled it off.
Video Capabilities: Professional Footage in a Tiny Form
DJI engineered the O4 Air Unit Pro to deliver cinema-quality video in environments where every gram and millisecond counts.
Professional-Grade Image Sensor
- A 1/1.3-inch CMOS sensor collects more light than typical FPV cams.
- Enhanced detail in shadow and highlight regions means more usable footage at golden hour.
- Ideal for pilots shooting in unpredictable lighting or pursuing commercial cinematography.
Slow-Motion at Its Best
- Shoots at 4K resolution and 120 frames per second.
- Allows buttery slow-motion footage with high pixel fidelity.
- Keeps action shots crisp even during rapid movement or post-production slowdown.
10-bit D-Log M Color Profile
- Records over 1 billion color variations.
- Gives filmmakers room to color grade extensively in post.
- Maintains highlight and shadow detail for stylized editing.
Compression That Doesn’t Compromise
- Uses H.265 codec for efficient file sizes with no loss in quality.
- Enables longer recordings without ballooning storage requirements.
- Ideal for marathon flight sessions or projects on tight memory budgets.
Wide View Without Warped Edges
- Offers a 155° ultra-wide field of view.
- Carefully corrected to minimize the usual fisheye distortion.
- Delivers immersive yet natural-looking footage.
Transmission Performance: Range and Clarity in Sync
Transmission is where most FPV systems fall short. Not the O4 Air Unit Pro.
Go Further, Worry Less
- Delivers up to 15km of signal range under ideal conditions.
- Maintains smooth communication even in RF-heavy areas.
- Expands the possibilities for location scouting and long-range explorations.
Low Latency for Fast Reflexes
- Features a Racing Mode with latency as low as 15ms.
- Allows instantaneous stick-to-screen feedback.
- Essential for high-speed racing and freestyle flights.
Sharp Live View
- Outputs 1080p video at 100fps to DJI goggles.
- Helps spot minute details in real time—trees, wires, gaps.
- Improves pilot confidence and flight precision.
Smarter Signal Handling
- Actively scans RF environments and adapts to interference.
- Maintains stable video even in cluttered, urban skies.
- Reduces dropout during critical moments.
Drone-Friendly Design: Small, Light, and Easy to Install
Performance is one thing—but DJI made sure the system fits nearly any build.
Barely There
- Weighs only 32 grams combined.
- Keeps flight times high and maneuverability sharp.
- Perfect for 3-inch class and sub-250g drones.
Tiny Footprint
- Camera: 25.6 × 20 × 23.3 mm
- Transmission unit: 33.5 × 33.5 × 13 mm
- Installs easily on compact frames without crowding internals.
Mounting Compatibility
- Supports both 20×20mm and 25.5×25.5mm patterns.
- No need for extra brackets or 3D-printed adapters.
Power Versatility
- Accepts 7.4V to 26.4V inputs (2S–6S LiPo).
- Works with nearly any drone powertrain without a regulator.
Built for the DJI Ecosystem
DJI has made sure the O4 Air Unit Pro plays nice with your existing gear.
Goggle Support
- Works with DJI Goggles 3, Goggles 2, Goggles Integra, and Goggles N3.
- Lets current DJI users upgrade without needing a full overhaul.
Controller Compatibility
- Fully supports DJI FPV Remote Controllers 2 and 3.
- Maintains mapping, telemetry, and custom configuration features.
Update and Expand Over Time
- Supports OTA firmware updates to enhance features.
- Configuration is accessible through DJI’s mobile app.
- Future accessories and software add-ons will continue expanding its utility.
Flight-Tested in the Real World
In varied conditions—from dense urban landscapes to forest trails—the O4 Air Unit Pro performs admirably.
- Urban Environments: Maintains strong signal despite buildings and RF congestion.
- Distance Flights: Degrades gracefully instead of cutting out abruptly.
- Obstacle Navigation: Punches through leaves, walls, and small structures better than older systems.
- High-Speed Flights: Keeps up with aggressive freestyle flying without glitching or lag.
- Weather Resistance: Survives moisture, heat, and cold, though not fully waterproof.
- Battery Efficiency: Runs cool and draws less power than you’d expect for its performance tier.
A New Standard for Aerial Storytelling
The DJI O4 Air Unit Pro isn’t just another digital transmitter and camera—it’s the clearest sign yet that FPV tech is moving into a new era. With uncompromising image quality, near-invisible latency, and compatibility across DJI’s growing hardware ecosystem, it’s as close as the FPV world has come to a no-compromise solution.
For pilots seeking the ultimate FPV experience—whether racing, filming, or exploring—the O4 Air Unit Pro is available now on Amazon and select DJI retailers.
It’s more than an upgrade. It’s the future of flying, and it’s finally here.
